Chord formula

Interval formula: 1 3 5 b7 9 11. A dominant with the 11th. In practice the 3rd is dropped — it clashes hard with the 11th — so it sounds almost like a 9sus4.

Chord tones

The 11th (a 4th an octave up) clashes with the major 3rd, so the 3rd is usually dropped, leaving a soft, open dominant.

Sound character

Open and soft, with no bite — essentially the same floating sus dominant.

Harmonic function

A dominant, usually a soft one. With no 3rd the pull is weaker, so it often just hangs.

Typical progressions

  • C#11 → C
  • F#11 (vamp)
  • C#11 – C#7

Guitar voicing advice

Leave out the 3rd. It works as Bb/C, or as a 5th-string root with b7, 9 and 11 stacked on top.
